WR-15 Waveguide Tee
The WR-15 Waveguide Tee is a precision-engineered waveguide component that splits a single millimeter-wave signal into two paths, or combines two signals together. It is specifically designed for the 50 - 75 GHz frequency range, serving as a critical building block in V-Band infrastructure.
Available in E-plane (series) or H-plane (shunt) configurations, the Tee creates a precision 3-port junction. Due to the physics of the junction, a perfect match at all three ports requires an internal matching post. WR-15 spans the 50-75 GHz V-Band. Its 0.148" x 0.074" dimensions are the standard for 60 GHz commercial backhaul networks and inter-satellite links (ISL) in low earth orbit constellations.
Key Features
Dual Configuration
Available in E-plane (series) and H-plane (shunt) configurations to meet different signal phase and power division requirements.
Precision Port Alignment
CNC-machined port interfaces with tight tolerances ensure accurate waveguide alignment and repeatable flange mating on all three ports.
Low Junction Loss
Optimized tee geometry minimizes mismatch loss at the three-port intersection, maintaining signal integrity across the full operating bandwidth.
Gold-Plated Construction
OFHC copper body with gold plating provides excellent conductivity, corrosion resistance, and consistent long-term electrical performance.

Frequently Asked Questions
What is a Magic Tee?+
A Magic Tee is a specialized 4-port component that combines an E-plane Tee and an H-plane Tee into a single unit. It acts as a 180-degree hybrid coupler, perfectly isolating the E and H ports from each other.
How is WR-15 used in space applications?+
WR-15 is the standard for Inter-Satellite Links (ISL) in V-Band. Because there is no oxygen in space to absorb the 60 GHz signals, satellites can transmit massive amounts of data to each other using WR-15 feed networks and high-gain antennas without interference from Earth-based signals.
Are WR-15 components difficult to manufacture?+
Yes. At 75 GHz, the wavelength is only 4 millimeters. A manufacturing defect of just 0.1 mm inside a WR-15 component acts as a massive impedance mismatch. All RF Essentials WR-15 products undergo strict metrology and vector network analyzer testing.
